A high-yield synthesis of 3,3-difluoroazetidines was developed by a monochlorohydroalane reduction of 3,3-difluoroazetidin-2-ones. The latter compounds were conveniently synthesized by a Reformatsky-type reaction of aldimines with ethyl bromodifluoroacetate.
通过对 3,3-二氟氮杂环丁-2-酮进行单氯氢醛还原,开发出了一种高产率合成 3,3-二氟氮杂环丁的方法。后一种化合物是通过醛亚胺与溴二氟乙酸乙酯的 Reformatsky 型反应方便地合成的。
